The hierarchy of planes is classified from low to high as follows: small plane, low plane, middle plane, high plane, top plane.

These planes, varying in levels, together form the Endless Plane, which is the entire universe we currently inhabit.

Small planes usually refer to those that have a plane barrier but lack powerful individuals within the plane.

Generally, the strongest entity a small plane can accommodate is Level 3 Life; any life form exceeding this level cannot enter a small plane, only their projection can.

If a life form exceeding Level 3 forcefully enters, it can easily cause a collapse of the small plane's world rules.

But in reality, life forms beyond Level 3 find it difficult to force themselves in.

Low planes refer to those where life within has developed to a certain scale and possesses considerable strength, including the presence of Level 3 Life individuals.

Such planes are essentially similar to small planes, the only difference being the power levels of life forms within and the presence of Level 3 Life.

The strongest life a middle plane can accommodate is Level 6 Life, and when a life in a low plane breaks through to become Level 4, it triggers the plane's advancement process.

When Level 6 Life in a middle plane becomes Level 7 Life, it propels the plane to become a high plane.

A high plane can accommodate the strongest entity as Level 9 Life, which is the limit for many planes within the Endless Plane.

Only when a high plane has at least one Level 9 Life can it be called a top plane.

...

Duke learned that the Wizard Plane is currently a middle plane and contains several Level 6 powerhouses.

However, none of these Level 6 powerhouses are on the West Coast; the Appalachian Continent only has one Level 6 powerhouse, and they are on the East Coast.

The Wizard Plane is currently on the path to becoming a high plane, but this step has been attempted for thousands of years without success.

Only when one of the Level 6 powerhouses within the Wizard Plane becomes a Level 7 powerhouse can the entire Wizard Plane become a high plane.

This would be a great benefit to all beings in the Wizard Plane, bringing immense advantages to the entire plane.

Even ordinary people would gain substantial benefits from the plane's advancement.

However, stepping forward is not easy, as the Endless Plane is extremely dangerous.

The Wizard Plane is, after all, just a middle plane and is far from being powerful within the Endless Plane, potentially being wiped out by a top plane at any moment.

The Wizard Plane's various factions control numerous low planes, small planes, and even middle planes.

These are the results of Wizard Plane's many years of campaigns, conquering other planes, plundering resources, and strengthening itself.

Duke realized that the Endless Plane is essentially a place governed by the law of the jungle, survival of the fittest.

"Wolves eat sheep without asking the sheep's name," Duke suddenly recalled this phrase.

To those low planes, the Wizard Plane is a wolf, an invader taking their resources.

But in front of stronger planes, the Wizard Plane is just a sheep.

The high-level factions within the Wizard Plane clearly recognize their own weakness and need to sharpen their teeth, make their claws sharper, and toughen their fur before a stronger wolf arrives.

All this is for survival and development.

The stronger a plane becomes, the more conspicuous it is within the Endless Plane, attracting the attention of other planes, thus inviting capable hunters.

The Wizard Plane is now in an awkward position, so close to becoming a high plane, yet unable to take that step.

This means they have some capability but are far from truly powerful.

The Wizard Plane has suffered many attacks from other planes, encountering several near-extinction crises along the way; it hasn't been easy.

After the class ended, Duke left the classroom, his mind still filled with fresh knowledge.

Only now did he have a complete understanding of the world; it's far grander than he imagined.

This knowledge doesn't offer substantial aid or improvement to him currently, but it broadens his perspective.

After leaving the learning area, Duke went to the marketplace and purchased several second-hand books, all related to planes.

In these books, he found the name of the Nightmare Plane.

The Nightmare Plane is a top plane and is among the stronger ones within top planes.

Seeing this, Duke broke out in a cold sweat, relieved he hadn't acted hastily these few days.

If his casual entry into the Nightmare Plane attracted the attention of powerful entities within, it could bring doom to the Wizard Plane.

With its current strength, the Wizard Plane can't possibly contend with a plane like the Nightmare Plane.

The Nightmare Plane is very peculiar; no one knows its exact location, and no one has ever seen this plane.

Yet the Nightmare Plane is ubiquitous because the dreams of every creature in the Endless Plane originate from this plane.

In essence, if you have nightmares, you might connect to the Nightmare Plane.

However, ordinary people's nightmares rarely connect to the Nightmare Plane and usually have little impact.

Some wizards speculate that the Nightmare Plane is fundamentally composed of the dreams of all creatures in the Endless Plane.

As long as there are beings in the Endless Plane who can dream, the Nightmare Plane will never be destroyed.

Reading this, Duke felt somewhat overwhelmed, realizing that the Nightmare Plane is virtually invincible, undefeatable from the start.

No one can defeat such an opponent; no wonder the Nightmare Plane is so powerful and elusive.

Looking at the Heart-shaped Earrings in his palm, Duke realized it's the conversion of the Nightmare Plane coordinates.

He even suspected this object is like a bait, intentionally released by the Nightmare Plane for fishing.

The more Duke thought about it, the more plausible this assumption seemed.

He's decided not to touch this item for the time being, as it involves power levels far beyond his current capabilities.

He stored the earrings into the Space Ring to study them later.

After returning to the dormitory, he continued using Meditation to substitute sleep, speeding up his practice and honing his skills rigorously.

Now that Duke understands the vastness of this world, he feels a growing sense of urgency.

In essence, he's like an ant in the grass to powerful life forms.

Through meditation practice during this time, the Deep Blue Tide Meditation Technique is finally ready to level up.
